About the 11-member RCM

The 11-member Regional Climate Model (RCM) provides projections of absolute future climate as opposed to changes relative to the 1961-1990 baseline (as with the UKCP09 projections). It should be noted that there is less support available on the use of the 11-member RCM compared with others UKCP09 products.

The 11-member RCM data is created using 11 variants of a climate model called HadRM3. Unlike the UKCP09 Projections, the 11-member RCM only represents projections from the HadRM3 model, and does not take into account any other model projections.
